Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8148, here are decompositions:

31 + 8117 = 8148
37 + 8111 = 8148
47 + 8101 = 8148
59 + 8089 = 8148
61 + 8087 = 8148
67 + 8081 = 8148
79 + 8069 = 8148
89 + 8059 = 8148

Showing the first eight; more decompositions exist.
